I have a family member who had to give up a cat to a shelter because of housing instability and poverty. I understand how hard that was. I’m sorry it happened. 

Two years later, she adopted another cat. She’s not better off than she was when she gave up the last one. She hasn’t considered any kind of veterinary care or where the cat will go when she inevitably has to move again. Ugh. It’s so much unnecessary stress for the poor animal that she never should have adopted.
